Aerated Bottom Drain 110mm

In order for this Bottom Drain to function, 110mm Solvent Weld Pipe must be used (please view our pipe identification chart for finding your correct pipe size)

When building a pond, the 9′′x 4′′ Bottom Drain and Dome is intended to provide a high-efficiency, low maintenance system since it removes sediments and trash from the pond floor.
It is better to use a gravity feed system because the solids are fed directly into your filter system for removal rather than being liquidised into tiny particles as they would be in a pond pump. The smaller the particles, the more difficult it is for your filter system to remove them, which leads to water of lower quality.
The 9′′ x 4′′ Bottom Drain's 110mm outlet provides a high water flow that creates an excellent "pull," eliminating trash from the pond's bottom.

Where is my bottom drain located?

Pond bottom drains are situated in the deeper parts of the pond and are found there.
Bottom drains are made up of a sump that is put into the bottom of the pond and connected to the pipework.

Multiple bottom drains can be installed along the floor of a pond to prevent any spots for sludge to build up.

Planning and Building

Bottom drains should be taken into consideration at the commencement of pond planning and installed when the pond is built since the pipe-work required for the building of a gravity-fed filter goes under the pond and is typically laid in concrete.
Setting up a bottom drain is significantly more effective than having a pump in the pond feeding a filter.
Bottom drains are much less likely to clog or be hindered by debris and can handle higher particles than the majority of pond pumps.

An included flange ring for the sump can be screwed onto its top lip.
If the pond is lined, a non-toxic sealant should be used to adhere the liner to the flange ring and the sump lip, forming a watertight seal.
The flange ring is not necessary if the pond is made of concrete.
The final rendered layer of the pond should be level with the top of the sump.
The top of the sump is separated from the dome by a space of typically 2 to 5 cm, which should prevent smaller pond fish from accessing the filtration system.

The pipes connecting the bottom drain to the filter should run as directly as possible, and any bends should have a big curved radius in order to achieve the highest flow rate and reduce the buildup of debris.

There isn't a Bottom Drain in my current pond.

Why Use A Bottom Aeration Drain?

The advantage of installing an aerator on your bottom drain is that the rising air bubbles create an uplift that circulates the water towards the bottom drain, increasing the bottom drain's ability to remove waste and debris from the pond by up to 30%.
It not only improves bottom drain performance but also aerates the water, creating a healthier environment in your pond.
